02 no power no codes
 

My uncles powerstroke on his way home one day just lost power he said intermittently it would lose power then come back alive. Real hard starts and sounds like a miss. He let it sit awhile and now it has no power at all truck will barely move if you can get it started. It will get up to about 40mph in a mile or two. I've been doing some research but do most of my work on Cummins trucks. Any advice? code reader isn't telling me anything. Only weird thing I saw monitoring it was engine load was at 0% all the time and maf as at 0. Line pressure was saying 5psi at idle and 95 when I stomped it. Thanks

Hard to start, no power
 

Did you check the cam shaft sensor? I had one go on my 99 Powerstroke.

No just been looking through posts, there seem to be a lot of problems with the harness through the valve covers. I'm just not use to these overly complicated power stroke systems.

idk if this will help, but I saw a video on youtube and the guy showed his screeners in the fuel tank and they were completely gummed up.. so it could be starving for fuel.
